Downvoting of hard tactic-puzzles?

#20 Agreed.

#13 People won't agree on what constitutes a good puzzle; there is a strong bias to upvote puzzles the player solved and downvote puzzles the player failed.

@hatchet:

It might be true that some high rated puzzles are really not difficult or at least I cant figure it out why it is rated like that.

Here is one example. This puzzle was rated 2230 and in my opinion should not be higher rated than 1800-1900.

I dont know what you can do wrong here because there is obviously only one playable move available and the follow-up is also easy to spot...

Its is played over 9000 times and had a low score of 130 points.

Bottom line: I highly recommend buying a puzzle book or using a proper tactics website instead of the lichess tactics.
@Nadastar: Yeah, people don't count the pieces I guess or whatever, playing Qxc5.

I can tell you since i just failed it (played the first winning move i saw, then didnt check for alternatives, same problem that has often been described here).

SPOILER:

"Qxc5 wins a piece, Black's attack is over after that and we are two pawns up" was what i immediately saw. So i played it. When lichess told me "wrong move" i instantly saw the "right" one.

This may actually be a good example of those high rated puzzles where people play the wrong-right move because it is the more eyecatching one. Only in this instance the right-right move is very much better than the alternative.

@hatchet:

I would not be so hard with lichess-trainer, I tried chesstempo as well but dont like it (dont know why but its not my taste) and puzzle-books are of course fine as well but I think lichess puzzles are worth trying them.

Maybe its just a matter of personal taste...

@scoreman:

Qxc5 does not win a piece. It wins nothing and the material is equal after Qxc5, dxc5, Bxh4, Bxf1, Kxf1.

White should be better due to pawn structure and piece activity but dont know if its already winning.

First thing I do before I even start calculating anything is to count material.... 1 pawn + another pawn + next pawn + knight + rook +..... helps allot... ;-)

#26 you are right of course, and i am guilty of just quickly playing a move after checking your link ;)

#27: It was not my intention to kill your tactic ratings by leaving nasty traps behind me...

The rating of puzzle 51022 is rapidly growing now. OMG what have I done! ;-))

A friend of mine gave me a hint and I checked it with engine. Indeed it seems that the best move after Ng7 given by Stockfish is Kh1! with an direct attack. After Bxf1, Rxf1 the open g-file will decide the game.

But its given as a mistake in the puzzle, so - sad but true - the puzzle seems to be wrong at the end: (http://de.lichess.org/training/51022)

How do one arrange the pieces on the chess board and ask Stockfish to analyse the problem given? I will be most grateful if someone could help me. Thank You.
